There are few subjects in the programming world that inspire as much partisanship as regular expressions. I've seen normally mild mannered developers fly into fits of psychopathic rage over the best regular expression for a phone number. I've watched blood spilled over what is the best way to regex an email address. So before you fashion a shiv out of an old mouse and a discarded motherboard, please let me qualify my intent. I don't suggest these are the best regular expressions for each of the items in question. I am not even sure what "the best" means in this context. I can say that these regular expressions have worked and I have the unit tests to prove it. I also whole heartedly invite you to comment, criticize, improve upon, and even ridicule what I offer here. However, in many cases I am just the messenger. Many of the regular expressions in this library have been gathered from sources long that I have long since forgotten and so I can take ownership of them only in an attenuated sense. So now that I have all the necessary qualifications out of the way, please enjoy and improve upon the code below.
